Setting the work profile

  1. In the Field menu, select Work profiles.

The active work profile is opened.

  1. Activate or deactivate the pulse width frequency modulation.
  1. Enter the target rate for full-area spraying. Please refer to the spray table and the nozzle manufacturer’s specifications.
  2. Open the Nozzle configuration.
NOTE
To ensure correct rate control, the nozzles and nozzle settings must be selected appropriately.
  1. Select nozzle 1.
NOTE
To ensure correct rate control, the flow rate must be set appropriately at 3.
  1. Set the nozzle colour.
  2. Set the flow rate at 3bar. Please refer to the spray table and the nozzle manufacturer’s specifications.
  3. Select the Droplet size classes.
  1. Set the maximum spray pressure for each droplet size class in accordance with the nozzle manufacturer’s specifications.
  2. Go back to the work profile configuration.
  1. Set the spray pressure for nozzle 1.

The optimum speed range and the droplet size class that can be achieved at the set spray pressure are displayed below the setting.

  1. Set the nozzle configuration for nozzle 2, nozzle 3 and nozzle 4. Set the spray pressure for nozzle 2, nozzle 3 and nozzle 4.
  2. Scroll to the next page of the work profile configuration.
  1. Enter the minimum and maximum spray pressure.
  1. Select the working width.
  1. Under Working width, enter the total working width in m.
  2. Under End nozzles, enter the width for the end nozzle control in m.

  3. To use edge nozzles:

    Select the desired edge nozzle type under Edge nozzle type. Confirm with .

The Manual part-width sections setting allows you to define part-width sections manually in order to control adjacent single nozzles together.

  1. Under Manual part-width sections, enter the number of manual part-width sections.
  2. Scroll to the next page of the working width configuration.
  1. Select Configure part-width sections.
  1. and select the part-width sections. Enter the width or number of nozzles for each part-width section.
  2. Save entries.

  1. To control manually defined part-width sections symmetrically on both sides of the boom:

    Activate Symmetrical part-width sections.

  2. To selectively activate or deactivate manually defined part-width sections:

    Select Activate part-width sections. Activate or deactivate part-width sections. Confirm.
  3. Go back to the work profile configuration.

  1. If pulse width frequency modulation is activated for the work profile:

    Leave the Minimum duty cycle setting at the default value of 30%. Do not make any changes without first consulting Customer Service.

If necessary, the behaviour of CurveControl when driving in curves can be adjusted as follows:

  • Normal metering: optimised metering in the inner and outer area, factory setting

  • Under-metering: tolerance of under-metering in the outer area when the optimised metering cannot be maintained.

  • Over-metering: tolerance of over-metering in the inner area when the optimised metering cannot be maintained.

  • Constant pressure: operation at a constant spray pressure despite adjusted metering

  1. To adjust the behaviour of CurveControl for driving in curves:

    Select the desired setting under Metering.
  2. Scroll to the next page of the work profile configuration.
  1. Switch on CurveControl

or

Switch off CurveControl.

  1. Save the work profile. Go back to the work profile selection.
